When I joined Thumbtack nearly three years ago, we had 25 engineers and were just beginning to scale the team (to nearly 140 engineers today!). Needless to say, we had to hire fast to scale. As we did, we quickly started noticing some problems in our interviewing process.
Hiring fast meant we had to train new interviewers fast—sometimes within weeks of starting the job. It became harder to get everyone to care about the same thing in debriefs. One interviewer would claim that “the candidate was a great coder; very methodical”, while another interviewer would say “too slow and didn’t know about X library”.
